| Abstract: | Based on the least square theory, the author deduced new formulae for calculating lattice parameters of all crystal systems, in which the correction of systematic error of X-ray powder diffraction pattern determination was taken into consideration, so the best estimates of the lattice parameters can be obtained. According to the deduced formulae, a PC-1500 computer program has been designed, which can be applied to alculate lattice parameters of each crystal system conveniently. |
